WRAPPING-MACHINE.

1' nil whom it may concern:

Beit' known that I, JAMES HENRY BRADY,

a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentuckv, have invented certain new and useful Improvements in mapping- Machines, of which the following is a specification. A A

Theinvention relates to machine for wrapping articles, such for instance as cakes of chewing gum, in paper and the like. Its objects are, generally stated, to provide a ma chine of simple and inexpensive construction that will automatically continuously perform the wrapping o erations neatly and quickly that will assem le a plurality of wrapped ar- 5 ticles into a ack, and place arubber band over them; t lat will wrap the articles in a waxed. paper anda printed label-paper and register the label perfectly on the cake. The i wrappers are in the form of a rolled web upon which the articles are fed and from which uniform lengths, constituting individual wra pers are severed. T iatembodiment of the invention shown inthe accompanying drawings is one that 'experience has demonstrated to be practical l and eflicient. The details of structure and arrangement Y may, however, be varied by I those skilled in such matters without departing from the princi les of theinvention. 3

completely wrappe cakeg and'Fig. 23,- the ctl imcpleted package with the rubberband ape The machine illustrated is especially de- 1 signed for wrapping cakes of chewing gum in p with the gum, and an outside labelsheet.

.The bed-plate 1, base-plate 2,v carriage 3, legs 4, and hopper 5 constitute the body ofthe machine, mounted on a suit able supportin frame. The waxed and, label sheets are fed tojthefmachine, preferably in'the form of H continuous'webs, fromrolls 6 and 7 (Figs. 1

and 2). The" label sheet 8, has perforations 64 (Fig. 15), located midway between the printed labels. The perforations act to effect registration of the printed'label per fectly upon the cake of gum (Fig. 23) and to that end control the operation of web severing devices. The wrapping "webs Sand 9, as they come from rolls 6 and 7, pass first under a spring arm 53 (Figs. 1 and 2), that produces sufficient slack in the webs to prevent their rupture in overcoming the inertia of therolls when the webs are intermittently 8o drawn along in the wrapping operation. From spring 53 the webs pass over a roller 52 and under a check spring, 51 (Figs; 1 and 2), I which prevents them from being drawn backward by tension of spring 53. They then pass under base-plate2 to' the'electric contact-apparatus (Figs. 1 and2), illustrated in detail in- F igs. 13 and 14, where the two webs i are separated, the waxed web 9, passing over a separating plate, and the perforated label web 8, passing, beneath it. n insulated spring 61, has an upturned pointed end that presses gentlyeagainst the label web 8,'a.nd a ooked contact, piece 59. As the'webs are moved along the pointed portion of s ring 61 5 slips into the perforations 64 in thela 1 web, thus elevating the contact-piece 59 into co'n-f tact with a corresponding contact-arm 60,

and completing an electric circuit "which efi'ects operation of the shearing knife' 67. too The contact-arm 60 may be adjusted by -means of ascrew'62 (Figs. 1,2,,13 and 14.), Then the webs are again mqved, member 61 is de ressed as perforation 64 passes on,,and the circuit is broken. From theelectric conr05 tact apparatus, webs 8 and 9 pass through a slot 65 (Figs. 14, 17, 18 and 19), inthe base- .plate to the top thereof just .in'front of,,the

fold; Fig. 22, a perspective view showing the 5 5;

hopper in which the cakes of gum are stacked, and as far forward as "the shearing knife 67. Just behind knife 67 a spring 57, (Figs. 16, 17, 18 and 19), in the base-plate serves to elevate the ends of the webs.

The carriage 3 side-plates (Figs.'3 and 16.)- joined by crosspieces 13 and 14, (Fig. 3), forming a rectan- I gular frame.

To the side-plates 3, at each end are secured guide-shoes 58 (Fig. 3), grooved to embrace and slide on the edges of base-plate 2; T he carriage is connected by a pitman 11 (Figs. 1, 2 and 3), w ith a crank 12, on a transverse shaft driven by a pulley 10. A cake-ejecting bar 15 (Figs. 1, 2, 3, 17, 18 and 19), is secured to the under surface of cross-piece 14 (Figs. 3 and 18) at the rear end of carriage 3, and to the front cross-piece 13 are secured a long shoe-arm 16 and a short shoe-arm 17, (Figs. 3, 4, 17, 18 and 19). The shoe-arm 16 is provided at its free end with a shoe 18 and a shoe-spring, 68, and the cake-holding springs 55 and 56 (Figs. 3, 17,

18 andlQ) are attached to the hopper, their free ends being adapted to press onbase plate 2.

When the carriage moves forward, it carries ejecting bar 15 (Figs. 17 and 19) which pushes from the ho per the bottom cake of gum onto the end 0 webs 8 and 9 and under rings 55 and 56 that press it firmly upon t e webs, the free ends of which are thrown up by spring 57. When the cake of gum is pushed forward it drops down over the abutment 70, so that it cannot be pushed back toward the hopper. As the carriage moves rearwardly shoe 18 comes in contact with the upturned ends of webs 8 and 9, folds them a over 11 on the cake, and finally the heel of the shoe webs against the cake. When the carriage 3 is moved forward again, shoe 18 carries the cake of m with it, (Fig. 19), and the folded over en 3 of the webs bemg held by spring 68 the webs are drawn forward with the cake.

- When shoe 18 has drawn the cake cutter slot 66 and carried the we 3 alo until the length f web between the rear en of the cake and cutter slot is the same as that folded upon the cake at the front; orwhen a perforation in the label-web is mid-way under the cutter or knife 67, the next perforation in the rear will have to come under the point of spring 61 (Fig. 14), the electric circuit is closed, magnet 1 (Fig. 16) attracts its armature carried by trigger 2, and knif '67 is formed of two lateral.

' lever 84 is stationary.

cam 82 1s tapered on its upper side to form an rops in behind thecake, the shoe-' spring 68 holding the foldedv portionof the ast' the being released is thrown down by its spring 6 and'serves the paper. The webs now remain at rest with their ends upturned by spring 67 (Fig. 19). Shoe 18, which has not paused, carries the partially wrapped cake over the inclined ledge-strip 71 (Fig. 17) and 'upon aplatform '73 (Figs. 9 and 17). Platform 72 is now flopped by the cam-mechanism illustratedln the upper portion of Fig. 9 and in Fig. 10. The mechanism for operating platform 72 .consists of bracket 83, attached to right-hand side of carriage 3, the right-angular lever 84 pivoted at the rear end to the bottom of base-plate 2, the cam-strip 82 is secured to bracket 83. the hinged camfiap 8 6, and the standard 85, fixed to lever 84 and carrying the platform. In Fig. 9. platform 72 is represented as elevated flush with the highest point of inclined abutment-strip 71, and lever 84 in corresponding position.

'The dotted lines in Fig. 9, and the detailview Fig. 10 represent the parts when the platform is dropped. It will be understood that cam 82 moves with the carriage and that The forward end of inclined plane and the rear end* is cut off square. -V\'hen the carriage moves backward, the square end of cam 82 strikes flap 86, foldin it back and passes on without elevating ever 84, and, when the cam has passed by, the flap springs into the path of the cam again. hen the carriage moves forward in the act of bringing a cake onto the platform, flap 86 slides upon the incline of the cam, is thus elevated and drops off when. the end of the cam passes from urlder it. The purpose of the platform is to furnish a smooth track for the partially wrappetLcake in transit and prevent displacement of the wrappers. If the cake were drawn over the ledge of strip 71, without platform 72 being elevatedpresser-spring, 68 would not hold the first fold of the wrappers properly. T he ledge is necessary in order to prevent the cake from moving back w th the foot and to elevate the' rear unfolded, ends of the wrappers preparatory to their folding over upon the cake by the presser-spring of foot 19. It will be'ilnderstood that at this point another cake of gum will have been ejected from the hopper and will be in position under springs -and 56. Carria e 3 is now moved rearwardly and while s 0e 18 recedes from the first cake lying on platform 72 it is held by a pair of spring-actuated presser-feet 24 and 25 ledge formed by ledge-strip 71 into position 1 wrappers of the first cake are folded forward l are made of small round wire and score the sides of the wrappers down snugly against gage cam-rollers 7-5 and 76 secured on the over the cake and over the previously folded ends by the presser foot. of shoe '19, the heel 19 which drops in behind the cake by reason of a groove in the ledge plate 71. and carries it forward under the scoring springs 22 and f 23 (Figs. and 19). These scoring springs the edges of thecake. and thus prepare them to be folded over.

Two lateral folding shoes. 20 and 21 (Figs.

3, 17, 18 and 19 are secured tothe free rear [ends of lever arms 23, 29, pivoted to basei plate 2 and normally spread apart by a spring: 30. On the outer sides of arms 28 and 29'are cam-strips 73 and 74 (Fig. 3), adapted toenguitle slioes 58 of the carriage. As the cari riage moves forward, cam-rollers 75 and 76 i press together arms 23 and 29 and hence 1 shoes and 21, theone shoe a little in ad- 5 'vance of the other, and thus the sides of the wrappers are folded snugly over the thin presser-spring of shoe 19 which is pressing down upon the previous folds of the wrapper E on the cake of gum. This completes the l folding operation. Shoe 19 now carries the folded cake on into the mechanism illustrated in detail in Figs. Hand '12. wrapped cake is deposited under a depressor I 32. which holds the folds of the wrapperi down firmly upon the cake and the presserspring. The carriage now recedes, the shoe 19 and its presser-spring are withdrawn, and the operations just described are repeated, shoe 18 having deposited another cake on platform 72,etc. A cam-strip 34,is attached 5 underneath cross-piece 13 of the carriage and f moves with the carriage. ()n the top and 111 1 the middle of base-plate 2, toward the front," between folding-shoe arms 28. 29 (Figs. 3,

11, 17, 1S and 19) visisecured a depressorspring31, the free ends of which extends forward over thereceptacle for the wrapped cakes and has a depressor-block 32, seemed to its under face. 011 the top of depressor- 1 spring 31 is hinged a depressor-cam- flap 33, 5 which is actuated bya spring 'so that it nor,; mally stands upright, in the position shown 1 in Figs. 11 and 17. Whenever cam-strip 34 is-drawn forward it drags the free end of flap 33 forward and depresses it against the aci tion of its spring (Figs. 18 and l9),l )ut, when released from strip 34, asis shownm the po-l e sition illustrated in Fig. 17, it flies up-and stands in the path of strip During the absence of strip 34 spring 31 raises depressor 32to the position shown by the dotted lines f The (Fig. 11) so that the wrapped cake may be deposited under it (Fig. 17). When now str p 34, is moved backward by carriage 3,

strip 34 engages flap depresses depressor 32 and carries cake 36 downward with it into the wrapped-cake-receiving apparatus. On the sides of this cake-receiving apparatus are arranged springs 37 and 3S, (Figs.,11 and 12), having their free ends bent, as illustrated, in such a manner that the cake 36 spreads them in passing downward, and they spring in over the edges of the cake so as to hold the cakev down firmlyupon a packing-platen 39, and at the same time' hold the folds of the wrapper down to prevent unfolding. Packingplaten 39 is mounted upon the top of a stem 40, which is adapted to move in a hollow standard 41, and has secured to its lower end a bracket 46 and a pin 47. A spring 48, is adapted to urge stem upward and thus hold the platen 39 always firmly against the j cakes 36.

It will be understood that as the foldedcakes are deposited under depressor 32 and depressed thereby, packing-'platen 39 is gradually depressed against the action of spring Stem 49 in passing downward,"

passes through a tripping platform 42, and a So I holding-platform 43, WlliCiLfilG pierced to accommodate the stem. Platform 42is hinged at its forward end in the forward leg 4 (Figs. 1 and 2), and platform 43 is hinged to platform 42 by means of hinge 50. Attached to the right-hand side-plate of carriage 3 is a bracket (Figs. 1, 2 and 11), which extends downward into proximity to platforms 42 and 43. ()n the lower end of bracket 80 is pivoted,bymeans of hinge 79, a'pusher 77, having an extended arm to which is attached a tension-spririg 78, which has a tjend'ency to cause the pusher 77 to stand out at right angles to the plane of bracket 80 and across I platform 42. The lower edge of pusher 77, however. normally extends below the edge of platform 42' and hence is prevented by said platform from moving out. It, therefore, normally moves back and forth with carriage 3 folded in and pressing against the righthand edge of. platforms42 and 43. A spring 44, presses platforms 42 and 43 upward (Figs. 11", 1 and 2). A stem 49, issecured in platform42, and passes lo'osely through a hole in platform 43. The stem pushesup platform 42, and a coil-spring 45, on stem 49 holds up platform 43. By this means platform 42 may rise and leave platform 43 'still dopressed by force applied to its free end.

To the rear of platform 43 is placed a pyramid-87 (F ig. 9), having its upper and lower upward. terminating in a stem 99.. It is yieldingly held in'its bracketagainst upward movement by a spring 97, which is bifurcated that of platform 42.

with a central longitudinal slot, extending from apex to base.

these four slots are four pusher-arms, 88, 1 having their forward ends notched, and piv- 'oted at their rear ends to apusher rod 90,

which, in ,turn, is secured by means of a bracket 91, to the right-hand side-plate3 of the carriage, thus causing arms 88 to move The bottom 1 in unison with the carriage. pusher-arm 88 is provided with a flap 96, which allows the pusherarm to drag while going backward, but, while going forward,

bears against the bottom of bracket 93 and lifts the arm up and thereby also lifts pyra-" mid 87 to provide space for arubber bandto pass between it and the bracket.

Returning now to the receptacle for the wrapped cakes (Figs. 11 and 12), it will be seen that, as packing platen 39 is depressed by the accumulating cakes 36, .it finally reaches and sinks into a socket, shown by dotted lines, in the uppersurface of platform 42. When depressed into this socket. until it bottoms therein the upper surface of the platen forms a continuous surface with As it is now further depressed, it carries with it platform$42, against the action of spring44, until platform 42 sinks beyond the lower edge of pusher 77.

The machine may be set so that every sixth cake, for example, will below the lower edge of pusher 77. It will be understood that, since platform '43 presses against platform 42, they form a continuous f upper surface at the rear end, and are both ports it (Fig. 9).

depressedtogethr. Pusher 77 now flies out across the platforms by the action of spring 78 and engages the six lowest cakesand carries them'back toward pyramid 87 (Fi s?! and 9) and deposits them in the mouth of the pyramid (Fig. 9). As soon as pusher 77 (Fig. 11) has passed the rear end of platen 39, the platen springs lowest ofthe remaining cakes 36 which remain lodged between springs in the bracket above. When pusher 77 has passed the rear end of platform 42 it springs'up into the position shown in Fig. 1 1, but'platform 43 is still held down by the pack of cakes 81 and sup- When carriage 3 is reci rocated pusher 77 engages theend of plat orm 42, now elevated, is folded in by it'and held in that position until another pack is formed depressed beyond its lower edge. The open end of pyramid 87 is adapted to accommodate a little less than half of the length of the cakes.

0nd the apex of the pyramid, and the rubi' band 94, which previously was suspended Adapted to move in depress platform 42.

It will be seen that flap 96 raises the lower arm and, through it, the pyramid above the bottom of its bracket, allowing the band to pass.

between it and the braclttfimrhat the same time, the upper arm 88 bears against shoe 98' on spring 97 and raises the spring so that the 1 upper part of the rubber band has a free pas-. sage. forward and out of its bracket by its'upturned apex bearing against the lug on the bracket which is shown holding the rubber :band at 95. When arms 88 havereached their forward limit, the rubber band springs over the base of g the pyramid onto and around the package 81 and releases itself from the notched'ends' of the arms.

and delivered to the apexof the yramid one at a time. This is accomplished by the rubber-band-separator, placed immediately above the sents the ru er band hopper. This hopper is secured ina pivoted bracket, 11. To the .ries the'ho per are attached two chains 12 of the letter A, and have their ends attached to a double bell-crank lever 13, pivoted on a stationary bracket and having a depending stem disposed in proximity wit I sidelate of carriage 3., At a suitable place on this side-plate is secured a projecting roller, 14, adapted to strike the sides of the stem of lever 13' alternately as the carriage reciprocates. It will be understoodv that the motion thus imparted to lever 13gives a jerk to chains 12: at each reci rocation, and thus, through lever 11, a 'ost ing motion to ho per 10. lodging the rubber bands in the. feeding them continuously to the separatorfi Immediately below the bottom of hopper 10 is a stationary laten, 17', which is slotted out to form a c annel 18, of curved shape, (Fi s).
